Abstract：The microwave,activated carbon and Fenton were applied to catalyze and oxidize the landfill leachate, the effects of different influential factors on the removal of landfill leachate were investigated. The results indicated that the removal rates of COD and NH3-N enhanced with the increase in AC dosage, microwave radiation time and microwave power. However, with the increase in Fe (Ⅱ) and H2O2 dosage, the removal rates of COD and NH3-N firstly increased then decreased; with the increase of pH value, the NH3-N removal rate increased significantly while the change of COD removal rate was not obvious. When the microwave power was 300W, pH value was 8, AC dosage was 9 g/L, Fe (Ⅱ) dosage was 0.02mol/L, H2O2 dosage was 7mL/L and radiation time was 6 min, the removal rates of COD, NH3-N, SS and turbidity could reach 68.22%, 78.08%, 78.55% and 99.02% respectively, the colour of the landfill leachate was removed from dark-brown to nearly colorless, the biodegradability (BOD5/COD) of the landfill leachate was improved from 0.21 to 0.45 after the treatment; moreover, the removal effects of different treatments on landfill leachate were compared, the results showed that the COD and NH3-N removal rates by microwave-assisted catalytic oxidation process were higher than other treatments significantly.
